Flutter Developers Who Can Also Write the Native Side
Dart engineers who ship to both stores from one codebase, keep state management consistent, and can write the Swift or Kotlin platform channel when Flutter alone does not reach far enough.
What should you look for when hiring a Flutter developer?
Look for three things beyond Dart fluency: consistent state-management judgement, since mixed patterns in one codebase are the most common cause of unmaintainable Flutter projects; performance awareness around widget rebuilds and list virtualisation; and the ability to write platform channels in Swift and Kotlin for capability Flutter does not cover natively. Anviam screens on all three and provides Flutter engineers on a rolling monthly term with onboarding in five to ten business days.

Flutter Developers Who Stop at the Framework Boundary Get Stuck
Every non-trivial Flutter project eventually needs something Flutter does not provide: a vendor SDK that ships iOS and Android libraries only, a hardware integration, a background behaviour that differs per platform, a native view embedded in a Flutter screen. At that point a developer who only knows Dart stalls, and the project either drops the feature or waits for someone who can write the Swift and Kotlin side.
So platform-channel experience is a screening requirement rather than a nice-to-have. It is also the honest answer to the "one codebase" promise: Flutter removes most of the duplication, not all of it, and a team that can cross the boundary when needed is what makes the promise hold. Alongside that we screen on state-management consistency and rebuild discipline, since those two determine whether the codebase is pleasant in year two.
What Our Flutter Developers Cover
Screened on the specific areas where Flutter projects tend to go wrong.
Flutter & Dart Depth
Widget composition, async patterns and null safety applied properly rather than worked around.
Consistent State Management
Riverpod or Bloc applied uniformly, not three patterns layered over each other by successive developers.
Platform Channels
Swift and Kotlin bridges for vendor SDKs, hardware and OS behaviour Flutter does not expose.
Rebuild & Performance Discipline
Controlling widget rebuild scope, virtualising long lists and profiling jank with the right tooling.
Offline & Local Persistence
Local storage with sync and conflict handling, so the app works when connectivity does not.
Dual Store Release
App Store and Play Store submission, signing, staged rollout and store policy handling.
Flutter Stack We Staff For
When to Hire Dedicated Flutter Developers
Two-Platform MVP
iOS and Android coverage needed quickly with a small budget and a small team.
Consolidating Native Apps
Separate iOS and Android apps that have drifted apart and cost twice as much to maintain.
White-Label Products
One codebase themed per customer, where maintaining native variants per client is untenable.
Internal Field Apps
Workforce and inspection apps where consistency across platforms is preferable to platform idiom.
Rescuing a Flutter Project
An existing codebase with mixed patterns, jank and abandoned dependencies.
Team Extension
An existing Flutter team needing extra senior capacity for a release push.

Common Questions About Hiring Flutter Developers
How much does it cost to hire a Flutter developer?
We quote a total monthly rate per engineer by seniority, inclusive of management, equipment, leave cover and the replacement guarantee. For teams weighing this against two native hires, a single Flutter engineer covering both platforms is usually the larger saving rather than the hourly rate difference — though that only holds if the app does not need extensive native work, which we assess honestly before recommending it.
Can a Flutter developer handle both iOS and Android release processes?
Ours do, and it is part of screening. Both stores have their own signing, metadata, privacy declaration and review requirements, and Play adds staged rollout mechanics worth using. A Flutter developer who has only ever handed builds to someone else for submission will stall at release, which is a poor time to discover the gap. We expect engineers to own submission end to end.
Do we need a native iOS or Android developer as well?
Usually not, if the Flutter engineer can write platform channels, which is why we screen for it. You would want dedicated native capability where the app is genuinely hardware-intensive — advanced camera processing, AR, a large vendor SDK with deep native integration — and in those cases we would question whether Flutter is the right framework at all rather than staffing around the mismatch.
How do you screen Flutter developers?
A practical exercise in an existing Flutter codebase rather than a greenfield toy app, because the real skill is working within someone else's patterns. We ask candidates to fix a rebuild performance problem and add a feature consistent with the existing state management, then discuss a platform-channel scenario. We also ask what they have shipped to both stores, since developers who have only built and never released miss a substantial part of the work.
Can Flutter developers work on our existing native apps too?
To a degree, and we would set expectations carefully. Flutter engineers with platform-channel experience can work in the Swift and Kotlin layers, which covers integration work and modest native changes. They are not a substitute for a dedicated native engineer on a large native codebase. If you have both a Flutter app and substantial native apps, we would propose staffing accordingly rather than claiming one person covers all three.
What if we later decide to move away from Flutter?
It is a real consideration and worth planning for from the start. Business logic, API clients and validation can be kept in Dart packages with clean boundaries so the domain layer is portable, and we structure projects that way as a matter of course. A UI rewrite would still be needed, but you would not be re-deriving business rules from a mixed codebase. We would also want to understand why the question is being asked, since it often points to a framework-fit issue worth addressing directly.
